ICS858012

PRELIMINARY

The ICS858012 is a high speed 1-to-2 Differential-

to-2.5V, 3.3V LVPECL Fanout Buffer and is a

member of the HiPerClockS™ family of high

performance clock solutions from ICS. The

ICS858012 is optimized for high speed and very

low output skew, making it suitable for use in demanding

applications such as SONET, 1 Gigabit and 10 Gigabit

Ethernet, and Fibre Channel. The internally terminated

families such as LVPECL, LVDS, LVHSTL and HCSL to be

easily interfaced to the input with minimal use of external

components. The ICS858012 is packaged in a small 3mm x

3mm 16-pin VFQFN package which makes it ideal for use in

space-constrained applications.

• Two differential LVPECL outputs

• One differential LVPECL clock input

• IN, nIN pair can accept the following differential input

levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL

• Output frequency: 2GHz (typical)

• Output skew: <15ps (typical)

• Part-to-part skew: TBD

• Additive phase jitter, RMS: TBD

• Propagation delay: 350ps (typical)

• Operating voltage supply range:

V

• -40°C to 85°C ambient operating temperature

• Availabe in both standard and lead-free RoHS compliant

packages
